| audiometry, evoked response | A form of electrophysiologic audiometry in which an analog computer is included in the circuit to average out ongoing or spontaneous brain wave activity. A characteristic pattern of response to a sound stimulus may then become evident. Evoked response audiometry is known also as electric response audiometry. (12 Dec 1998) |
| auditory brainstem response audiometry | An electrophysiologic measure of auditory function utilizing responses produced by the auditory nerve and the brainstem to repetitive acoustic stimuli. (05 Mar 2000) |
| biological response modifier | <pharmacology, oncology> A substance used in adjuvant therapy that takes advantage of the bodys own natural defense mechanisms to inhibit the growth of a tumour. (16 Dec 1997) |
| biological response modifiers | Substances that stimulate the body's response to infection and disease. The body naturally produces small amounts of these substances. Scientists can produce some of them in the laboratory in large amounts and use them in cancer treatment. Also called BRMs. (12 Dec 1998) |
